Rice
Rice is a crop of grass berumpun. This plant originated daru two continents, namely Asia and the West African tropical and subtropical regions. Extensive rice cultivation in Indonesia is estimated at 11-12 million ha, which is scattered in various typologies of land such as rice (5.10 million ha), rainfed (2.10 million ha), field (1.20 million ha), and tidal land (Susanto, et al., 2003).

There are 25 species of Oryza. The most famous is O. sativa with two subspecies. First, adalaj Japonica (rice fur) grown in subtropical areas. Second, indica (rice CERE) planted in the tropics. Japonica adaptation that develops in some areas in Indonesia referred to as javanica subspecies.
Research activities of rice plants with a mutation technique has been widely applied, BATAN own institution has succeeded in creating new varieties through breeding with this mutation techniques. Examples of such success is the release of some rice varieties include; Atomita 1, Atomita 2, Atomita 3, Atomita 4, Situgintung, Cilosari, Woyla, Meraoke, Kahayan, Winongo, Diah Holy, Yuwono and Mayang. Several varieties have been used in rice crossbreeding program. (See more at http://jai.staff.ipb.ac.id/tag/sorghum/)
